World History
Dissolved Empires
Empires that either don't have a convenient modern equivalent, don't have a widely recognized successor state, or are so ancient that successor states aren't relevant. The USSR actually does fall into those descriptions but it's rather insufficient to treat it as just a chapter of Russian history.
Empires are distinguished from international organizations by the number of states with effective agency. The EU is multi-polar, while the USSR was not.
Dissolved States
States that either don't have a convenient modern equivalent, don't have a widely recognized successor state, or are so ancient that successor states aren't relevant. Yugoslavia is a bit iffy but I include it anyway.
Excludes empires.
Historic Regions
Regions that have historic context, but not a historic state.
International Wars
- Italian Wars of Independence
